AISI T4 steel DIN 1.3255 bars W18Cr4VCo5 steel china price per ton
AISI T4/ DIN 1.3255/W18Cr4VCo5 steel.
a.Description:
This alloy is a High Speed, tungsten type tool steel. It is a deep hardening alloy capable of Rockwell C 64 hardness.
Applications:
Generally used as cutting tools, broaches and cold extrusion punches, turning and milling cutters for roughing work.
Soft Annealing:
Heat to 820-850°C, cool slowly in furnace to 550°C then air. This will produce the maximum Brinell Hardness of 265.
Stress:
Stress relieving to remove machining stresses should be carried out by heating to 600-650oC, holding for one hour at heat, followed by aircooling. This operation is performed to reduce distortion during heat treatment.
Hardening:
Stress relieving to remove machining stresses should be carried out by heating to 600-650oC, holding for one hour at heat, followed by aircooling. This operation should be performed to reduce distortion during heat treatment.
Tempering:
Tempering temperature: 2 x 560-580oC. Hardness after tempering is 64-65 HRC.
